TNP-470 Suppresses the Tumorigenicity of HT1080 Fibrosarcoma Tumor Through the Inhibition of VEGF Secretion From the Tumor Cells

Angiogenesis inhibitors are a novel class of promising therapeutic agents for treating cancer. TNP-470, a systemic analogue of fumagillin, is an angiogenesis inhibitor capable of suppressing the tumorigenicity in several animal models even though the mechanisms of action have not been completely clarified. In the current study, we investigated the effects of TNP-470 on human fibrosarcoma cells in vivo and in vitro. The administration of TNP-470 could suppress the tumorigenicity of HT1080 fibrosarcoma tumor. The conditioned medium from HT1080 fibrosarcoma cells treated with TNP-470 inhibited the proliferation and migration of human endothelial cell line, HUVEC and ECV304. The concentration of VEGF in the conditioned medium from HT1080 cells treated with TNP-470 was lower than that of the cells without TNP-470 treatment, indicating that TNP-470 downregulates the secretion of VEGF from HT1080 cells. These findings strongly suggest that the direct action of TNP-470 on sarcoma cells inhibits angiogenesis through the downregulation of VEGF secretion and this angiogenesis suppression resulted in the inhibition of tumorigenicity of HT1080 fibrosarcoma tumo

Interactive Rakuchu Rakugai-zu (Views in and Around Kyoto)

This book constitutes the refereed proceedings of the First International Conference on Culture and Computing, C&C 2020, held as part of the 22nd International Conference on Human-Computer Interaction, HCII 2020, in July 2020. The conference was planned to be held in Copenhagen, Denmark, but had to change to a virtual conference mode due to the COVID-19 pandemic.Rakuchu Rakugai-zu is a screen painting illustrating in and around Kyoto created from the beginning of 16th century until 17th century. As in the Funaki Version of Rakuchu Rakugai-zu everyday lives of over 2, 000 people in Kyoto are vividly painted, the painting is a good material to learn their customs in early 17th century in Kyoto. However, it is difficult to understand the details of the painting, if background information is not provided. How to document such information and how to provide people such information would be crucial for the future of museums. To cope with this, we are carrying out a project to develop the interactive Rakuchu Rakugai-zu, Funaki Version. Firstly, we digitize the painting with ultra-high resolution. Secondly, using historical books regarding the customs of that era., we identify clothes and behaviors of each person in the painting and linked them to the person in the painting. Thirdly, we develop the technology to provide such information interactively using text or voice. Fourthly, we develop present Funaki Version including various manga characters so that we can compare old and present customs of people. Integrating these contents and technologies we are now developing the interactive Rakuchu Rakugai-zu, Funaki Version

Development of Practical Wrist Rehabilitation Robot by Mirror Effect

The authors have developed wrist rehabilitation robot for hemiplegic patients. The robot is much effective for repetitive rehabilitation, and useful for patients. Mirror effect control system is developed based on the experience that a patient can easily move a limb while moving a limb on the other side. The effectiveness is successfully confirmed by the practical test in the hospital.3rd International Conference on Advanced Materials Design and Mechanics, ICAMDM 2014; ; 23 May 2014 through 24 May 201

Development of a rehabilitative training robot for both wrists

The authors developed a rehabilitative training robot which detects and analyzes the intention when a person tries to move a wrist with a biological signal, such as muscle action potential, and makes a wrist movement as one\u27s intention. It consists of a grip for wrists, an actuator, a biological signal primary means, biological signal processing part, and a training controller. Due to its small, compact size, training can be performed in a small space at a hospital or home. The new system which can conduct both wrists training is successfully developed for practical uses.2013 7th ICME International Conference on Complex Medical Engineering, CME 2013; Beijing; China; 25 May 2013 through 28 May 201
